NimbleBit's Ian Marsh has announced on Twitter that his Pocket Gamer Bronze Award-winning freemium build-'em-up Tiny Tower is set to be updated with missions, which will allow you to earn batches of the game's premium currency Tower Bux.
As you can see for yourself in the image below, each mission will task you with stocking a specific amount of several products (the two figures on the left), and will reward you accordingly should you meet the requirements (the number on the right).
What happens if you don't have the necessary floor in your tower to stock one of the products?
Well, according to Marsh: "You can gift products to friends if they don't have the necessary floors."
There isn't currently a set release date for this update, but it's expected to hit the App Store "soon". In the meantime, you can grab Tiny Tower for your iPhone and iPad for free.
